Disk array and its access right control method and device, server and server system

Abstract

The invention provides a disk array and its access authority control method and devices, server and server system, in which, the method includes: the request for the access of logic volume sent by the disk array receiving server, this access request must have the server identifier, logic volume identifier and access attribute; the disk array query indicates the access authority list of logic volumes access authority for the disk array of servers; according to the access authority list, when the access authority corresponding to the server identifier and the logic volume identifier can't support the access attribute, the disk array refuses the server to access the logic volume in the mode recorded in the access attribute. The invention may effectively protect the disk array against the virus intrusion, avoid the malicious juggle of data saved on the disk array by Hacker, thus improve the safety of data on the disk array.

Description

technical field [0001] The invention relates to the access authority control technology of computer storage media, in particular to a disk array and its access authority control method and device, server and server system. Background technique [0002] With the development of computer technology and the increasing requirements of users for storage performance, the storage media of computer systems have gradually developed from early floppy disks and built-in hard disks to the current external disk arrays. A disk array is a system formed by combining multiple hard disk drives according to certain requirements, and the entire disk array is uniformly managed by the array controller. Compared with the existing storage media, the disk array greatly improves the storage capacity of the computer system, and, because the multiple disk drives that make up the disk array can work in parallel, the data transmission rate is improved, thereby improving the working performance of the comp...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that: the prior art does not restrict the specific access rights to the disk array. All permissions of the volume, including unnecessary write permissions, have at least the following problems: it is impossible to prevent viruses from invading the disk array, and it is also impossible to prevent hackers from maliciously tampering with the data stored on the disk array, and the security of data on the disk array cannot be guaranteed ; In addition, the existing technology is to set its access authority when the logical volume is assembled (mount) before the logical volume is used, or to set its access authority through the file system after the logical volume is mounted. In the process of using the logical volume, it cannot be Change the access permissions of the logical volume set by the above two methods to achieve inflexibility
